Russian forces are on the move near the border with Ukraine...what's going on with this?

2nd Russian region bordering Ukraine switching to wartime mode, comprehensive mobilization exercise in Belgorod oblast too.

This is somewhat surprising.

Let me explain my thinking.  I've heard from readers about Putin's falling ratings in the polls and thought nothing of it.  Trump has had low ratings for the majority of his term and it was no big deal.

Some other readers were stating that we should be ready for some type of event to bring "patriotic fever" to the Russian populace to raise his numbers.

Again I thought nothing of it.

Then I saw a report on main stream news talking about his numbers earlier today and then saw this in my Twitter feed.

Could there be something to this?  Could the Russians be close to conducting "further operations" in Ukraine?

Seems like a VERY risky move but I have no view of Russian politics.

Is this possible?
